K5 = mid-size sedan replacing Optima
K4 = compact sedan replacing
Forte.
K3 = sub-compact sedan replacing Rio.
About the only connection this new K4's silhouette has to the Stinger is the sloping roof to the rear, but it's not clear it's even a liftback/hatchback. Judging by the short hood line and the short "prestige distance" (between front wheel arch and front door), this is FWD. Most likely with an ICE, and a hybrid option, with a wheelbase around 106" (same as
Forte). Nice to see Kia not abandoning small affordable cars, but a Stinger replacement this is not.
